Which of the following equations have no solution? select all that apply. a) |x| = -9 b) |x| = -7 c) |x| = 93.2 d) |x| = 5

Since Modulus of any real number is a positive Real number.

That is modulus is defined as

| x |= x, if x>0

and -x , if x<0.

=0 , if x=0.

|x|≠ -9,

and , |x|≠-7,

∵ modulus of real number is always Positive.

So, option A  |x| = -9

and Option B,|x| = -7

are equation having no solution.

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.
